... Another note, I didn’t know until this week that Petra was the city known as Sela in the Bible, and it is the capital city of the ancient nation of Edom.
The Edomites made inroads against the Kdm of Judea, but were themselves pushed out of Edom by the Nabataeans.
Other than some pagan altars on some hilltops and such (those are very old) the Nabataean ruins are about the oldest thing still visible at Petra. They are Hellenistic, borrowing Greek styles, and dating from the period after Alexander the Great, and through Roman and Byzantine times. Calvin College (Grand Rapids MI) hosted a special exhibit of the art of Petra back when King Hussein was still alive, definitely was in my top two of ancient stuff that has come through GR.
The structures which were standalone (iow, not carved into the cliff faces) were (as the vids noted) partially or wholly demolished by the big quakes, and the Romans had seen the advantage of controlling the city for its convergence of trade routes, so the population became another dependency of Rome, and Roman styles started to predominate.
